    [PATCH] cleanup bio_map_user and helper · 3bec8a5a
    Jens Axboe authored
    Bart did this patch, I changed it a bit. Basically it cleans the mapping
    interface up a bit, and adds a little helper to set up the request from
    the bio.
    
    In addition, it fixes a long standing bug where bio_map_user() would
    call blk_queue_bounce() without the direction bit being set, auch.
    
     - Abstract out bio request preparation
     - Have bio_map_user() set data direction (fixes bug where blk_queue_bounce()
       is called without it set)
     - Split bio_map_user() in two
